BUNCHER ATTACHMENT Specification of Letters Patent.

FOR MOWING-MACHINES.

Patented Aug. 14, 1906.

To ZZZ whom it may concern:

Be it known that I, NELsoN G. HANNA, of Kokomo, county of Howard, andState of Indiana, have invented a certain new and useful BuncherAttachment for Mowing-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which like numerals refer tolike parts.

The object of this invention is to provide improvements in theconstruction of buncher attachments for mowing-machines so as to renderthe same practical and satisfactorily operative.

This buncher attachment belongs to the type of machine wherein a rake ismounted at the inner end of the axle or side of the inner drive-wheel,as shown in my former ap plications for side-delivery bunchers, Serial.No. 109,848, filed June 2, 1902, and Serial No. 151,515, June 15,1.903.

One improvement herein resides in the means for moving and holding therake during its movement so that the rake will closely approach andparallel the cutter-bar.

Another novel feature consists in the means for effecting the rakemovement.

Another novel feature consists in the manner of mounting the platformwhereby it can be folded along with the rake without difficulty.

These and the other features of the invention will appear from theaccompanying drawings and the following description and claims.

In the drawings, Figure 1 is a plan view of the machine with the tonguebroken away. Fig. 2 is a front elevation of the machine with the tonguein cross-section. Fig. 3 is a plan view of the platform, cutter-bar,drive-wheel, and rake mechanism, parts being broken away and the rakemechanism being shown near its rearward limit of movement, otherpositions of the rake being shown by dotted lines. Fig. 4 is a frontelevation of what is shown in Fig. 3, parts being broken away and therake being shown elevated and on its return movement. Fig. 5 is avertical longitudinal section of the axle and driving parts of themachine on a large scale, parts being broken away. Fig. 6 is the same,showing I the rake-supporting means in the upward or elevated position.Fig. 7 is a side elevation of the platform and platform-supportingmeans, the cutter-bar and axle being shown in cross-section. Fig. 8 isan end elevation of the driving means on an enlarged scale, differentpositions of the long gear being shown in dotted lines. Fig. 9is a frontelevation of the machine with the tongue in section, showing the machinewith the rake and platform folded up. Fig. 10 shows a modifiedconstruction of what appears in Fig. 5. Fig. 1 1 shows a modifiedconstruction of what is shown in Fig. 6. Fig. 12 is a plan view of theinner ends ofthe rake-bars and the means on which they are mounted, therake-bars being partly broken away.

In detail the drawings herein show the drive-wheels 10 and intermediatesleeve 11, on which the tongue 12 is mounted; There is also shown anaxle 13, that is driven by the drive-wheels by means of the clutchmechanism 14, common in such machines. A cutter-bar 15 is connected withthe tongue or frame of the machine by braces 16 and 17. and the knife 18is driven by the pitman-rod 19' and the knife-driving means 20. All ofthe foregoing parts are old and common and may be made in any suitableway, as my invention consists in a mower attachment adapted to besecured to the inner or cutting end of the axle of the machine, as willhereinafter appear. 1

Turning to Figs. 5 and 6, the axle 13 is shown extended beyond the innerdrive-w heel 10, and the extreme end of said axle is reduced somewhat indiameter. Upon the axle adjacent the hub or clutch-cover 21 of the wheel10 a stationary frame 22 is loosely mounted and held from lateralmovement by collars 23, secured on the axle. Said frame has adownwardly-extending portion, to which a cross-bar 24 is secured, asshown in Fig. 7. This bar is horizontal and extends longitudinallyof themachine and at each end has a downwardly-extending bar 25,-and aplatform 26 is connected with said downwardly-extending bars by hingedmembers 27, as shown in Fig. 7. This construction is to permit theplatform to be folded up and to support the inner edge of the platform.while the machine is in use.

ed on the axle, I have pivoted a stirrup 30, as

shown in Fig. 7. This stirrup is pivoted at its lower end andis limitedin its outward movement by stops 31. (Shown in Fig. 7.)

This permits said stirrup to be turned inward toward the drivewheel, asshown in Fig. 6. Upon said stirrup I pivot the upper and inner end of acurved frame-plate 32 by the bolt 33, as shown in Fig. 12. The upper andinner end of said frame-plate 32 is normally horizontal, as shown inFig. but said plate is curved downward and outward, as therein shown.The upper and inner end of said frame-plate is widened by therearwardlyextending plate 34, or it may be widened in any other manner,and to the rear of such widened portion or plate 34 I mount the mainrake-supporting bar 35 between the vertical ears of the bracket 36, sothat said rake-bar may have vertical oscillatory movement, but nohorizontal movement independent of said frame-plate 32,-the purposebeing that such rake-bar shall be moved laterally by the movement ofsaid frame-plate 32. As shown in Figs. 1 and 2, the rake-bar 35 extendsoutward and downward and by means of the bolt 37 is pivotedsubstantially centrally to the top of the rake 38. An auxiliary rakebar40 is similarly mounted on the top of the stirrup 30 by means of abracket 41, pivoted on said stirrup. Said rake-bar is formed similar toand extends parallel with the rake bar 35 and is pivoted to an arm 42,extending forwardly from the rake 38. The rake-supporting bar 35 is atits inner end supported by the bracket 36 and the plates 34 and 32, soas to support the weight of the rake somewhat and hold it out offorcible contact with the platform. The stops 31 assist in accomplishingthis result, as they prevent the stirrup from passing outward beyond thevertical position.

The rake is actuated and moved by the movement of the lower end of theframe-' plate 32, which carries a long movable endlessbevel-rack 45,which is externally toothed and meshes with a bevel-pinion 46, mountedon the outer end of the axle 13. Said rack is rigidly secured to theframe-plate 32 by means of a screw-bolt 47, which passes through avertical slot 48 in said plate, as seen-in Fig. 5. As shown in Fig. 8,there are two ribs 49 on the outer face of the endless movable rack,between which the lower end of the frame-plate 32 is secured, thepurpose of such construction being to firmly unite said two .partstogether so that said rack Will have no play independently of theframe-plate 32. Said movable rack 45 is always horizontal and is held soby said plate 32 and travels in the manner indicated in Fig. 8, beingmoved by the pinion 46 in the directions indicated by the arrows. As therake is sweeping the bunch across the platform the movable rack is inthe position shown in full lines in Fig. 8- that is, on the under sideof the pinion. As the rake is discharging the bunch from the platformthe movable rack is in the position shown by the dotted lines on theright side of Fig. 8. During the return movement of the rake and whilethe same is elevated the movable rack is in the position shown by thedotted lines in the upper part of Fig. 8. When the rake is moveddownward into position near the cutter-bar, the movable rack is in.

the position shown by the dotted lines at the left side of Fig. 8. Saidmovable rack is held in mesh with the pinion 46 by the frameplate 32,the outward and downward movement of which is limited, as heretoforestated,

by the stops 31, that prevent the stirrup 30 from moving outward beyondthe vertical position. (Shown in Fig. 5.) The frameplate 32 is assistedin holding the movable rack in mesh with the bevel-gear by a pin 50,extending outward from and secured to an arm 51 from a band 52,loosely'surrounding the inner or hub portion of the pinion 46 ad j acentthe clutch member 53. Therefore said arm 51 and pin 52 are in the natureof a crank, turning on and independently of the pinion 46 and clutchmember 53. The pin extends and works loosely in a longitudinal recess 54in the inner face of the movable rack. Said recess approaches withinsubstantially the same distance of the outer surface of said rack notonly along the bottom and top, as shown in- Fig. 10, but also the samedistance from the ends, the purpose being that said pin shall hold, orrather aid in holding, the movable rack in mesh with the pinion 46 atall times. Therefore. the pin 50 moves independently of the movable racklongitudinally through the recess 54 in said rack, and'when the rack ison the under side, as shown in Fig. 5, the pin holds it up against thepinion. It holds the rack down when it is above the pinion, as shown inFig. 6, although in that position the strain on the pin 50 is not verygreat, because gravity assists in holding the rake in mesh with thepinion. When the ends of the rack come in mesh with the pinion, as shownin Fig. 8, the pin 50 is of service in holding the rack in mesh with thepinion as the rack'passes about thepinion. Therefore as the machineoperates, the axle, through the pinion 46, moves the rack 45 around saidpinion, as indicated in Fig. 8, and gives to the lower outer end of theframe-plate 32 a substantially elliptical movement, as indicated by thedotted line in Fig. 8, and such movement of the frameplate 32communicates a corresponding movement to the rake, and the verticalmove- IOC ment of the frame-plate as it moves about the ends of itselliptical course elevates and lowers the rake. The upper position ofsaid frameplate and rake-bars is shown in Figs. 4, 6, and 11.

The mounting of the rake-bar 35, in connection with the plate 34 and theframe 22, and also the regulating-bar 40 with the rake 38, holds andmoves the rake substantially according with the lines indicated in Fig.3. In other words, the lengths of the rake-bars 35 and and their pivotalconnections are relatively such that when the frame-plate 32 reaches itsforward limit of movement as the rake passes forward and. downward overthe pinion the rake will be parallel with the cuttor-bar and closeenough thereto to rake the material from the front part of the platform.As the frame-plate 32 passes rearward the rake will be moved rearwardand it will assume an angle to the cutter-bar that increases graduallyas it moves to the rear, so that as it reaches the rear side-deliveryedge of the platform it will be substantially parallel with such edge ofthe platform and nearly at a right angle to the cutter-bar, and whilethe outer ends of the rake-bars remain substantially the same distanceapart the inner ends will be moved apart slightly as the rake moves tothe rear.

- The clutch consists of a clutch member 53 integral or rigidlyconnected with the pinion 46 and another clutch member 153, that has ahub 253 integral with it, said clutch member and hub being splined onthe spindle 72 and the member 153 adapted to frictionally engage themember 53.

The frame 22 has a brace-plate secured to it and extending around theforward portion of the drive-wheel 10 and secured rigidly to the side ofthe tongue or frame of the machine. Upon said plate at 61 a clutchlever62 is fulcrumed with one end extending across the tongue under aguiding-strap 63, and the other end is provided with a yoke 64,partially surrounding the hub 25-3 of the clutch member 153, splined onthe spindle 72. A spring 66 (seen in Fig. 1) is connected at one endwith the clutch-lever 62 and at the other end with the frame of themachine, so that said spring, which is contractile, will throw saidclutch members into engagement, and the clutch members are disengaged bythe foot of the operator pushing the lever 62 forward A washer 67 isplaced between the clutch member and the adjacent collar 23. While ;hemachine is being moved from one place 10 another without cutting, therake can be phrown up into the position shown in Fig. 9 LIlCl held bythe hooked rod 68, and the platorm can be thrown up, as shown in Fig. 9,LIlCl held by the hooked bar 69.

A modified form of a part of the construciion isshown in Figs. 10 and11. There a supplemental hub 70 is secured to the side of thedrive-wheel 10, with the reduced portion.

of the supplemental hub resting upon the extreme end of the axle 13. Theaxle in this form is of the usual length and not extended, as shown inthe other form. 71 is a pin through the axle.- In the reduced portion ofthe supplemental hub there is a spindle 72, secured so that the rotationof the wheel and the supplemental hub will cause the rotation of thespindle just the same as the axle in the other form. The frame 22 ismounted on the reduced portion of the supplemental hub between theenlarged portion thereof and a collar 23. Otherwise the construction 'isexactly the same as what has been described. In other words, this rakemechanism is shown detachably secured to and supported by the axle onlyor the axle and wheel, as in Figs. 10 and 11. The supplemental hub isnot only secured to the wheel, but rests on the end of the axle.
